10 years ago I heard “you’d better read all the floppy disks you’ve got now because you won’t be able to do it later.” You might do better with better hardware, you might not. This thing can get at the raw data

which might let you get most of the bits from a bad block. See

I can also recommend the KryoFlux. I had some floppy diskettes from a /very/ obscure computer, a Devtronix Model 264 pipe organ computer that recorded artists live, that also used the 3 1/2" form factor. It was able to completely recover all the data from them, and combined with the HxC 2001 Floppy Emulator, get everything onto a modern SD card format.
GreaseWeazle[0] is where it's at now. KryoFlux was all we had before, but GW has overtaken it, and is open source proper.
Neat! Thank you for the info on that one. Bookmarked!
Before I spend well over $100 importing that device, I previously was thinking of brining up a 2001 era motherboard with a USB stack and can natively host the drives, but the 486 that has sat unused may be a solid option. I presumably can find a way to transfer data to a modern system over serial cable or something.
